I noticed that your location is Argentina; I see that spelled Sumac here, but I assume we're talking about the same thing.

It's quite a coincidence, because I was just researching Sumac yesterday. I found this web site (poison-sumac.org) devoted entirely to Poison Sumac!
Apparently, Poison Sumac is even more toxic than Poison Ivy or Posion Oak.
The good news is that Posion Sumac is very rare, occuring only in Wetlands ... and, apparently, "very wet" Wetlands at that.

That's good news for me, because I needed to cut some Staghorn Sumac (not poisonous) out of a fence row.
If I even "look at Poison Ivy or Posion Oak the wrong way", I get a rash eek... so, I know I don't ever want to tangle with Poison Sumac.
